PROCESS FOR PRODUCING FUSION PROTEINS COMPRISING SCFV FRAGMENTS BY A TRANSFORMED MOULD

Abstract: The present invention provides a process for producing fusion proteins comprising ScFv fragments by a transformed Aspergillus mould containing a DNA sequence encoding the ScFV fragment under control of at least one expression and/or secretion regulating region derived from a mould selected from the group consisting of promoter sequences, terminator sequences and signal sequence-encoding DNA sequences or functional derivatives or analogues thereof. Such regulating region can be derived from the endoxylanase II gene (exlA gene) of Aspergillus niger var. awamori present on plasmid pAW14B or can be the combination of both a promoter and a signal sequence-encoding DNA sequence derived from a glucoamylase gene ex Aspergillus plus a terminator sequence of a trpC gene ex Aspergillus. Preferably a fusion protein comprising "secreted mould protein - (KEX2 -) ScFv" is produced. Also provided are new products comprising an ScFv fragment or fusion product thereof, compositions, e.g. consumer products, containing both old and new products so produced. Preferably the ScFv fragment recognizes a compound present in the human eco-system, such as microorganisms or enzymes. Such compounds can be present in the oral cavity, e.g. involved in the formation of plaque, caries, gingivitis, periodontal diseases, or bad breath, or on the human skin, e.g. involved in the formation of malodour, inflammation or hair loss, or can be a hormone, e.g. HCG.

Description: Title: Process for producing fusion proteins comprising ScFv fragments by a transformed mould The present invention relates to the production of a Single Chain antibody fragment (ScFv fragment) by a transformed mould. In this specification an ScFv fragment stands for a variable fragment of a heavy chain connected by a linker peptide to a variable fragment of a light chain. Background of the invention It has been described that ScFv fragments can be produced in various transformed microorganisms, but with various degrees of success. For example, from WO 93/02198 (TECH. RES. INST. FINLAND; Teeri c.s.) published 04.02.93 it is known that ScFv fragments can be produced and secreted in several host organisms (although it is only exemplified in E. coli and S. cerevisiae), provided that a special linker is used between the heavy chain and the light chain fragments. That linker comprises a flexible hinge region of a naturally secreted multidomain protein or an analogue thereof not being homologous to either of the heavy or light chain fragments. This WO 93/02198 is incorporated herein by reference. A serious limitation of the method disclosed in WO 93/02198 is the low production level shown, which is far below the production level required for the application of ScFv fragments in consumer products at a reasonable price. Examples of such consumer products include detergent products, food products, and products for the personal care of people like toilet soap and under arm hygienic products. Thus there is a need for a more universal high-yielding production system for ScFv fragments. The production of an ScFv fragment in E. coli bacteria gives relatively low yields and there is a need for solubilization and subsequent renaturation of the proteins formed inside the bacteria, which makes this method not attractive for production of antibody fragments that need be used in relatively large amounts (see page 3, lines 5-23 of WO 93/02198). When attempting to produce various ScFv fragments in yeasts using expression systems, that have produced various heterologous enzymes in amounts sufficient for economical application in consumer goods, the present inventors found that the ScFv fragments were not secreted or only in very minute quantities. This appears to be in agreement with Example 2 on pages 29-31 of WO 93/02198 which relates to the production of an ScFv fragment in yeast without indicating the amount produced. Although in WO 93/02198 many alternative linkers are mentioned, it is stated on page 6 of WO 93/02198 that "... there are no published reports of the analysis or design of secretable linker peptides." and "... there are no published examples to date of novel fusion proteins with added heterologous linker sequences which are secreted to the culture medium of the host." In another recent publication, namely in WO 92/01797 (OY ALKO AB), published 06.02.92, the production of immunoglobulins in the mould Trichoderma is described. In Example 20 on pages 83-85 and Figure 27 the construction and expression of a functional gene encoding a single chain antibody containing variable regions of both a light and heavy chain linked to each other by a flexible hinge region of CBHI is described (CBHI is cellobiohydrolase I present in large amounts in the culture medium of Trichoderma reesei; see page 3 of WO 92/01797). The gene was under control of a T. reesei cbhi terminator and either a T. reesei cbhi promoter (plasmid pEN401) or an Aspergillus gpd promoter (plasmid pEN402). The plasmids were transformed to Trichoderma reesei strain RUT-C-30 (ATCC 56765) and the transformants were grown in two different media. Expression of immunoreactive single chain antibodies was tested from culture supernatants but no results were mentioned. Thus it was not demonstrated that any amount of single chain antibodies was actually formed. This conclusion is in agreement with a later related publication of Nyyssδnen et al. ex NTT Biotechnical Laboratory, Finland (1993) in which partially the same experiments are described with plasmids pEΝ304, pAJ202 and pEN209 encoding the 23.3 kD light chain, the 23.9 kD heavy Fd chain and the 73.2 kD CBHI-heavy Fd chain, respectively, which plasmids are also exemplified in WO 92/01797. In this publication only the production of a separate light chain or a separate heavy chain, as such or as a precursor, by a Trichoderma reesei strain is described, but the production of an ScFv fragment containing a light chain connected via a linker peptide to a heavy chain is not described. Therefore, there is still a need for an alternative production and secretion system for ScFv fragments in a mould that gives at least a reasonable yield of the desired ScFv fragment. The present invention provides such production using a transformed mould of the genus Aspergillus. According to M. Ward et al. (1990), see also GENENCOR's WO 90/15860 published 27.12.90, the production in Aspergillus of a desired protein and subsequent secretion can be improved when a fusion protein comprising the desired protein and a mould protein is produced. This was exemplified with the production of prochymosin fused with its amino terminus to the carboxyl terminus of A. awamori glucoamylase. However, that publication does not give any suggestion that such an approach would also be suitable for the production of ScFv fragments, which are known as compounds presenting great difficulties when one attempts to obtain their production and secretion by a microbial host (see the above mentioned WO 93/02198). In UNILENER's not prior-published WO 93/12237, now published 24.06.93 and claiming a priority date of 09.12.91, a process for the production and secretion of a desired protein by a transformed mould is described, in which the expression and/or secretion regulating regions are derived from the endoxylanase II gene (exlA gene) of Aspergillus niger var. awamori present on plasmid pAW14B (see Figure 3 of WO 93/12237), which is present in a transformed E. coli strain JM109 deposited under the Budapest Treaty at the Centraalbureau voor Schimmelcultures in Baarn, The Netherlands, as N° CBS 237.90 on 31 May 1990. In a preferred embodiment the desired protein can be part of a fusion protein comprising the desired protein preceded at its NH 2 -terminus by at least part of the endoxylanase II protein. No mention is made of the production of ScFv fragments. Summary of the invention The present invention provides a process for producing fusion proteins comprising ScFv fragments by a transformed mould, in which (a) the mould belongs to the genus Aspergillus, and (b) the Aspergillus contains a DNA sequence encoding the ScFv fragment under control of at least one expression and/or secretion regulating region derived from a mould selected from the group consisting of promoter sequences, terminator sequences and signal sequence-encoding DNA sequences, and functional derivatives or analogues thereof, optionally followed by a proteolytic cleavage step for separating the ScFv fragment part from the fusion protein. In one embodiment the "at least one expression and/or secretion regulating region derived from a mould" comprises the combination of both a promoter sequence and a signal sequence-encoding DNA sequence derived from a glucoamylase gene ex Aspergillus plus a terminator sequence of a trpC gene ex Aspergillus or at least one functional derivative or analogue thereof. In another embodiment the "at least one expression and/or secretion regulating region derived from a mould" is selected from a promoter, a signal sequence-encoding DNA sequence and a terminator sequence derived from an endoxylanase gene ex Aspergillus, especially from the endoxylanase II gene (exlA gene) of Aspergillus niger var. awamori present on the above mentioned plasmid pAW14B or at least one functional derivative or analogue thereof. In a preferred embodiment of the present invention the DNA sequence encoding the ScFv fragment forms part of a chimeric gene encoding a fusion protein, whereby said DNA sequence encoding the ScFv fragment is preceded at its 5' end by at least part of a structural gene encoding the mature part of a secreted mould protein, especially a mature Aspergillus protein, e.g. the mature glucoamylase protein or the mature endoxylanase protein. If the ScFv fragment in the fusion protein is connected or bound to said secreted mould protein or part thereof by a proteolytic cleavage site, e.g. a KEX2-like site, it is possible to remove the mould protein or part thereof from the ScFv fragment, so that the resulting antibody fragment is as small as possible, which can have significant advantages in applications. In this case the process according to the invention includes a proteolytic cleavage step for separating the ScFv fragment part from the fusion protein following the production of the fusion protein containing the ScFv fragment. It was found that production levels of at least 40 mg ScFv fragment per litre, or even at least 60 mg/1, and a highest yield of slightly more than 90 mg/1 could be obtained (see Table 2 below), but it is envisaged that after further optimization at least 150 mg/1 can be achieved by cultivation in shaked flasks. Further, production levels of more than 150 mg ScFv fragment per litre were already obtained with cultivation in a fermenter; it is therefore envisaged that after further optimization at least 250 mg/1, or even at least 500 mg/1, and probably more than at least 1 g/1 will be obtainable . The invention also provides new products comprising an ScFv fragment or fusion product thereof obtainable by a process according to the invention. Such new product can be one in which the ScFv fragment is a modified ScFv fragment comprising complementary determining regions (CDRs) grafted on the framework regions of the variable fragments of an other ScFv fragment that is well expressed and secreted by a lower eukaryote, especially a mould of the genus Aspergillus. The invention also provides a composition, in particular consumer products of which examples are given above, containing a product produced by a process according to the invention or a new product as described above. According to a special embodiment of the invention the ScFv fragment recognizes a compound present in the human eco-system, which compound can be a microorganism, an enzyme or another protein. One preference is for compounds present in the oral cavity, and more preferably for compounds involved in the formation of plaque, caries, gingivitis, periodontal diseases, or bad breath. Another preference is for compounds present on the human skin, more preferably compounds involved in the formation of malodour, inflammation or hair loss. Another special embodiment of the invention relates to a composition, which can be used for diagnostic purposes and in which the compound is a hormone, especially human chorionic gonadotropin (HCG). According to another embodiment of the invention the ScFv fragment recognizes a compound present in the eco-system of domestic and agricultural animals which compound can be an animal feed component, an enzyme or another protein, or a disease causing agent. According to still another embodiment of the invention a composition is provided in which the ScFv fragment recognizes a compound that has a positive or negative SUBSTITUTE SHEET ( RULE * 9f relationship with a disease or disorder and can for example be used for detection and/or targeting purposes. The invention also relates to a composition according to the invention which can be used in the chemical, petrol or pharmaceutical industry as a catalyst or for detection purposes. Although the invention was developed on the basis of the production of ScFv fragments in a mould of the genus Aspergillus, as will be illustrated in the Examples below, it is envisaged that the invention will also be applicable to other moulds, especially selected from the genera Mucor, Neurospora, and Penicillium.

Detailed description of the invention It has now been found that the development described above by M. Ward et al. (1990) and in WO 90/15860 (in which the gene .encoding the desired protein forms part of a chimeric gene further comprising a gene encoding the glucoamylase protein) as well as the above described preferred embodiment of the invention described in UNILENER's above mentioned not prior-published WO 93/12237 (in which the gene encoding the desired protein forms part of a chimeric gene further comprising a gene encoding at least part of the endoxylanase protein) can be applied advantageously for the production of ScFv fragments, so that the desired protein is the ScFv fragment. This is particularly so, when in the resulting fusion protein a proteolytic cleavage site is present between the secreted mould protein part or fragment thereof and the ScFv part. A preferred cleavage site is a KEX2- like site as described by Fuller et al. (1988), Contreras et al. (1991) and Calmels et al. (1991), but other cleavage sites can also be used provided that they are not present in the ScFv fragment. Other cleavage sites can be selected on the basis of the method described by Matthews & Wells (1993). In the Examples given below the pro part of the prepro-glucoamylase protein comprises a KEX2-type recognition site, see Example 2.4 (i). ScFv fragments that recognize microorganisms present in the oral cavity or on the skin of human beings are important in the framework of this invention, because they have potential to inhibit the growth or metabolism of these microorganisms. Certain microorganisms present in the oral cavity are thought to be involved in the formation of plaque, caries, gingivitis or periodontal diseases, etc., whereas microorganisms on the human skin are involved in, amongst others, the generation of malodour. The ScFv fragments prepared according to the invention may exert their action either as such, or bound to other compounds that have an inhibitory effect on said microorganisms. It is also envisaged that according to the present invention other modified ScFv fragments can be made by grafting a complementary determining region (CDR) on the framework regions of the variable fragments of an ScFv fragment that is well expressed and secreted in Aspergillus; compare grafting of CDR's on human im- munoglobulins as described by e.g. Jones et al., (1986). These CDR's can be obtained from common antibodies. Both the binding properties of a CDR and the remainder of the ScFv fragment can be optimized by random or directed mutagenesis. Thus in a process according to the invention CDR's originating from one antibody can be grafted on the framework regions of the variable fragments of another ScFv fragment. Some ScFv fragments or fusion products thereof produced by a process according to the invention may be old, but many of the ScFv fragments or fusion products thereof will be new products. Thus the invention also provides new ScFv fragments or fusion products thereof obtainable by a process according to the invention. The products resulting from such process can be used in compositions for various applications. Therefore, the invention also relates to compositions containing a product produced by a process according to the invention. This holds for both old products and new products. Instead of the combination of an exlA promoter, an exlA signal sequence-encoding DNA sequence, and an exlA terminator exemplified in Examples 3 and 5, also other combinations can be used e.g. an exlA promoter, an glaA signal sequence- encoding DNA sequence, and an exlA terminator as exemplified in Example 7, but in general a selection can be made from any mould-derived promoter, mould- derived signal sequence-encoding DNA sequence, and mould-derived terminator sequence as expression and/or secretion regulating regions. A specific embodiment is a combination of both a promoter sequence and a signal sequence-encoding DNA sequence derived from a glucoamylase gene ex Aspergillus plus a terminator sequence of a t C gene ex Aspergillus. The secreted mould protein forming part of a fusion protein according to the invention can in general be derived from any secreted mould protein in addition to SUBSTITUTE SHEFT (RULE 26) the exemplified endoxylanase II protein ex Aspergillus niger var. awamori (see Examples 3 and 5) and the exemplified glucoamylase ex Aspergillus (see Example 7). Table 2 in Example 2.6.1b shows that the highest expression and secretion yield was obtained when the mould protein was composed of its prepro part followed by an appreciable part of its mature protein, which was connected to the ScFv fragment by again the pro part of the mould protein containing a KEX2-like cleavage site. A small linker peptide may be situated between the ScFv fragment and the KEX2-like cleavage site (see plasmids pUR4159 and pUR4163 and derivatives) or between the latter and the part of the mature mould protein. Thus in its broadest sense the invention provides a process for producing fusion proteins comprising ScFv fragments by a transformed mould, in which the mould belongs to the genus Aspergillus, and the Aspergillus contains a DNA sequence encoding the ScFv fragment under control of at least one expression and/or secretion regulating region derived from a mould selected from the group consisting of promoter sequences, terminator sequences and signal sequence- encoding DNA sequences, or functional derivatives or analogues thereof. The invention will be illustrated by the following Examples. Example 1 Isolation of the antibody gene fragments encoding the V H and V L regions and the construction of ScFv genes. The isolation of RNA from the hybridoma cell lines, the preparation of cDNA and amplification of gene fragments encoding the variable regions of the heavy (N H ) and light (N L ) chains of the antibodies by PCR, was performed according to standard procedures known from the literature (see e.g. Orlandi et al, 1989). The general procedures described in the Examples were performed according to Sambrook et al., unless otherwise indicated. After cloning the N π and N L gene fragments and determining the nucleotide sequence, they can be used to construct expression plasmids encoding e.g. Fv or ScFv antibody fragments. In the ScFv antibody fragments, the N H and the N L chains are connected via a peptide linker. This is achieved by constructing a (chimeric) gene in which the gene fragments encoding the N H and N L chains are connected with a nucleotide sequence encoding the linker peptide. The order of the variable chains can be N H -linker-N L or N L -linker-N H . In the following experiments the peptide linker with the sequence (GGGGS) 3 is used (SEQ. ID. NO: 1). 1.1 Construction of ScFv anti-lysozyme Plasmid pScFv-LYS-myc was obtained from G. Winter and was described by S. Ward et al., (1989). This pUC19-derived plasmid contains a gene fragment encoding the V H and N L fragments of the anti-Hen egg white lysozyme antibody D1.3. The N H fragment is preceded by the PelB secretion signal sequence, the N H and N L fragments are connected via the (GGGGS) 3 peptide linker (SEQ. ID. NO: 1) and the N L fragment is extended with an 11 amino acids myc-tag. The nucleotide sequence (SEQ. ID. NO: 2) and the deduced amino acid sequence (SEQ. ID. NO: 3) of the H dIII-EcoRI fragment encoding the ScFv fragment of the monoclonal anti-lysozyme antibody D1.3, preceded by the PelB signal sequence and followed by the myc-tail are given below.

A pregnancy test kit based on the detection of HCG in urine by using monoclonal antibodies was developed by Unilever and is marketed by UΝIPATH under the trade name Clearblue®. Gene fragments, encoding the variable regions of the heavy and light chain fragments from the monoclonal antibody directed against the human chorionic gonadotropin were obtained from a hybridoma cell line in a way as described above. Subsequently, these HCG N H and N L gene fragments were cloned into plasmid pUR4129 by replacing the corresponding Psil-BstEll and Sαcl-Xhol anti-lysozym gene fragments, resulting in plasmid pUR4138. The nucleotide sequence (SEQ. ID. NO: 7) and the deduced amino acid sequence (SEQ. ID.

The 3'-part encodes the last 5 amino acid residues of the variable part of the antibody light chain. The resulting plasmid was named pUR4153. Plasmids pUR4154 and pUR4156 were obtained in the following way: After digestion of plasmid pUR4129 (Example 1.1) with Pstl and Xhol, an about 0.7 kb DNA fragment was isolated from agarose gel. This fragment codes for a truncated ScFv-LYS fragment missing DNA sequences encoding the 5 N-terminal and 5 C- terminal amino acids. In the same way an about 0.7 kb Pstl-Xhol fragment was isolated from plasmid pUR4138 (Example 1.2), which encodes for a similarly truncated ScFv-HCG fragment. In order to fuse the ScFv encoding fragments with the glaA secretion signal- encoding sequence, the obtained fragments were cloned into pUR4153. To this end plasmid pUR4153 was digested with Pstl and Xhol, after which the about 4.1 kb vector fragment was isolated from an agarose gel. Ligation with the about 0.7 kb Pstl-Xhol fragments resulted in plasmids pUR4154 (ScFv-LYS) and pUR4156 (ScFv-HCG), respectively. 2.2 Construction of pAN52-10 pAN52-10 (Figure 1) was used as starting vector for the construction of the Aspergillus expression cassettes. This plasmid was constructed as follows: In pAN52-6.VotI (Nan den Hondel et al, 1991) the Ncol site located in the glaA promoter of A. niger Ν402 (about 2.7 kb upstream of the ATG) was removed by cleaving with Ncol and filling in with Klenow polymerase, resulting in pAΝ52- 6NotI delta Ncol. After digestion of pAΝ52-6NotI delta Ncol with NotI and partial digestion with Xmήl an about 4.0 kb Notl-Xmή glaA promoter fragment was isolated. Three-way ligation of this pAΝ52-6NotI delta Ncol fragment (1) with an about 3.4 kb Notl-Ncol fragment (2) of pAΝ52-lNotI (Nan den Hondel, C.A.M.J.J. et al; 1991), comprising the A. nidulans trpC terminator (Punt, J.P. et al; 1991) and pUC18-sequences, and with a synthetic Xmήl-Ncol fragment (3) comprising the 3'- end of the glaA promoter to the ATG initiation codon, resulted in plasmid pAΝ52- 7NotI. The nucleotide sequence (SEQ. ID. NO: 13-14) of this synthetic Xmήl-Ncol fragment is given below. 5'- GCT TCC TCC CTT TTA GAC GCA ACT GAG AGC CTG 3 ' - CGA AGG AGG GAA AAT CTG CGT TGA CTC TCG GAC — Xjzml AGG TTC ATC CCC AGC ATC ATT ACA CCT GAG C TCG AAG TAG GGG TGG TAG TAA TGT GGA GTC GGT AC iVcoI After isolating both the about 4 kb Notl-Ncol fragment (comprising the glaA promoter) and the about 3.4 kb Notl-BamH fragment (comprising the pUC18 vector and the trpC terminator) from pAN52-7NotI, the fragments were ligated together with the Ncol-BamHl linkers containing an EcoRN site and an H dlll site and having the following nucleotide sequences (SΕQ.

Ligation of the about 4.0 kb Notl-Hindlll glaA promoter fragment of pAN52-9 with an about 3.3 kb Hind ll-Notl fragment of pA 52-6NotI containing both pUC18-sequences and an about 0.7 kb trpC terminator fragment of A. nidulans resulted in pAN52-10 (Figure 1). 2.3 Construction of pUR4155 and pUR4157. Plasmid pAN52-10 was digested with Ncol and Hindlll and the dephosphorylated vector fragment of about 7.5 kb was isolated. The Ncol site is located downstream of the glaA promoter and coincides with the ATG initiation codon. The plasmids pUR4154 and pUR4156 (see Example 2.1) were digested with Ncol and H dIII and the about 0.8 kb fragments coding for the ss-glaA and the ScFv were isolated. Ligation of the obtained fragments resulted in plasmids pUR4155 and pUR4157, respectively (Figure 2). In these plasmids the expression of the ScFv fragments is under the control of the niger glaA promoter, the 18 amino acid signal sequence of glucoamylase and the A.' nidulans trpC terminator. 2.4 Construction of ScFv expression cassettes using part of glucoamylase as a secretion carrier. i) Construction of pUR4159 and pUR4161. Expression cassettes encoding a fusion protein consisting of the glaA prepropart, the first 514 amino acids of the mature glucoamylase Gl protein ("glaA2" protein), and the ScFv fragments were constructed. In these cassettes the "glaA2" protein and the ScFv fragment were intersected by a sequence which encodes the propeptide of glucoamylase (Asn-Nal-Ile-Ser-Lys-Arg; SEQ. ID. NO: 45) and which comprises a KEX2-type recognition site (Lys-Arg). To obtain these vectors, plasmid pAN56-7 (Figure 3) was constructed by insertion of a 1.9 kb Ncol-EcoKV fragment of pAN56-4, comprising part of the A. niger glaA gene into the about 7.5 kb Ncol- EcoRN fragment of pAΝ52-10. Plasmid pAN56-4 was not prior-published but its description is now available in the publication of M.P. Broekhuijsen, I.E. Mattern, R. Contreras, J.R. Kinghorn & C.A.M.J.J. van den Hondel in Journal of Biotechnology 31, No.2 (1993) 135-145, which is incorporated herein by reference; a copy of the draft paper was attached to the priority documents. To obtain in-frame fusions of the "glaA2" protein and the ScFv fragments plasmids pUR4154 and pUR4156 were digested with EcoRI and Pstl, after which the vector fragment of about 4.8 kb was isolated from an agarose gel. The vector was ligated with a synthetic EcoRl-Pstl fragment having the following nucleotide sequence (SΕQ. ID. NO: 17-19).

From the resulting plasmids, pUR4158 and pUR4160, the EcoRN-Hwdlll fragments (about 0.75 kb) were isolated and ligated into the EcoRN-HmdIII fragment of ρAΝ56-7 (about 9.3 kb), resulting in pUR4159 and pUR4161 (Figure 4, in which the DNA encoding the 24 amino acid prepro glaA part in the neighbourhood of the Ncol site was not indicated). In the resulting protein the "glaA2" part and the ScFv part are connected by a peptide comprising a KΕX2 cleavage site. ii) Construction of pUR4163. In a similar way a vector was constructed with an expression cassette encoding a fusion protein consisting of the "glaA2" protein (preceded by its prepro part) fused to ScFv-lysozyme and intersected by a factor Xa recognition site. The EcoRI-Pstl vector fragment (about 4.8 kb) of pUR4154 was ligated with a synthetic EcoRI -Pstl fragment having the following nucleotide sequence (SΕQ. ID. NO: 20-22). factor Xa spacer I S I Ε G R G G S AAT TCG ATA TCG ATC GAA GGT CGA GGC GGA TCC GC TAT AGC TAG CTT CCA GCT CCG CCT AGG .EcoRI -EcoRV BamEI — N-term ScFv — Q V Q L Q — CAG GTG CAG CTG CAG — GTC CAC GTC G Pstl This EcoRI- s l fragment was used to replace the fragment encoding the glaA signal sequence and to allow an in-frame fusion to the "glαA2" gene. In the encoded protein the "glaA2" part and the ScFv part are connected by a peptide comprising a factor X cleavage site. From the resulting plasmid pUR4162, the EcoRN-Hzndlll fragment (about 0.75 kb) was isolated and ligated into the pAΝ56- 7 vector fragment (about 9.3 kb), resulting in pUR4163. 2.5 Aspergillus transformation The constructed vectors can be provided with conventional selection markers (e.g. amdS or pyrG, hygromycin etc.) and the fungus can be transformed with the resulting vectors to produce the desired protein.

The amdS Notl fragment was obtained by flanking the EcoRI fragment of pGW325 (Wernars K.; Ph.D. thesis 1986) with the following synthetic oligonucleotides. 5 '- GGCCGCTGTGCAG -3 ' (SΕQ. ID.

NO: 24) NotI ΕCORI The constructed pUR41..NOT vectors (pUR4155NOT, pUR4157NOT, pUR4159NOT, pUR4161NOT and pUR4163NOT) were subsequently transferred to Aspergillus niger var. awamori ATCC 11358 ( = CBS 115.52) and a mutant strain Aspergillus niger var. awamori # 40 (WO 91/19782) which has been obtained by mutagenesis of A. niger var. awamori. Transformation with pUR41NOT plasmids was carried out as described in WO 91/19782 or by means of co-transformation with plasmid pAN7-l according to Punt PJ. and Van den Hondel C.A.M.J.J. (1992). pA 7-l comprises the hygromycin resistance gene of E. coli flanked by Aspergillus expression signals. The yield of A. niger var. awamori (mutant #40) protoplasts was 1-5 x 10 7 /g mycelium and the viability was 3-8%. Per transformation 3-8 x 10 5 viable protoplasts were incubated with 10 μg plasmid DNA purified by the Qiagen method. A. niger var. awamori mutant #40 AmdS + transformants were selected and purified on plates with minimal medium and acetamide or acrylamide as sole nitrogen source. Direct selection resulted in up to 0.02 mutant #40 transformants per μg DNA. No A. niger var. awamori transformants were obtained. Co-transformation of the mutant #40 strain was performed with a mixture of one of the pUR41..NOT plasmids and pA 7-l DNA in a weight ratio of 7:3. pA 7-l co-transformants were selected primarily on minimal medium plates containing 100-150 μg/ml hygromycin, followed by selection on plates with acetamide. The frequency of Hm R colonies was about 2 transformants per μg, however only 5% of the Hm R colonies grew well on plates with acetamide. A. niger var. awamori mutant #40 transformants obtained by direct selection on plates with acetamide are called AWC. Mutant #40 co-transformants growing well on acetamide are called AWCM. The following number of (co-)transformants were further analyzed: Number of transformants Number of co-transformants AWC4155* 3 AWCM4155 3 AWC4157 7 AWCM4157 1 AWC4159 2 AWCM4159 5 AWC4161 2 AWCM4161 2 AWCM4163 2 * 4155 indicates the presence of plasmid pUR4155NOT in the mutant #40 strain. 2.6 ScFv production by Aspergillus transformants Analysis of Aspergillus niger var. awamori mutant # 40 transformants containing ScFv-fragment encoding sequences after culturing in medium with maltodextrin as an inducer. AWC and AWCM transformants were grown in minimal medium (0,05% MgS0 4 , 0,6% NaN0 3 , 0,05% KC1, 0,15% KH 2 P0 4 and trace elements) with 5% maltodextrin (Sigma Dextrin Corn type I; D-2006). Media were sterilized for 30 min at 120°C. Fifty ml medium (shake flask 300 ml) were inoculated with 4 x 10 5 spores/ml, followed by culturing in an air incubator (300 φm) at 30°C for different periods. Medium samples were taken after 45 to 50 hours and analyzed by SDS- PAGE followed by Western blot analyses. Furthermore a quantitative functional test was carried out by performing a Pin-ELISA assay. 2.6.1 Medium of ScFv-LYS and ScFv-HCG transformants 2.6.1a Western blot analysis and Coomassie Brilliant Blue-stained gels Western blot analysis of medium samples of AWC(M)4155 (18 a.a. glaA signal sequence-ScFv-LYS) (co-)transformants -in which anti-serum directed against Fv- LYS was used- revealed a band with a molecular mass of about 31 kDa which is absent in the medium of the mutant strain #40 (Figure 5). The presence of this band, which runs at the position of a protein with the expected size, points at secretion of ScFv-LYS in the culture medium. In medium of several AWC(M)4159 (prepro-"glaA2"-KEX2-ScFv-LYS) (co-trans¬ formants a similar, much stronger, band was found indicating a more efficient secretion of ScFv-LYS by these transformants. This protein band was also visible on Coomassie Brilliant Blue-stained gels. In medium samples of AWC(M)4157 (18 aa. glaA signal sequence + ScFv-HCG) a faint band was found, while the band in medium of AWC(M)4161 (prepro-"glaA2"- KEX2-ScFv-HCG) (co-)transformants was clearly visible (molecular mass about 31 kDa). The aspecific signals were identical to the ones obtained with ScFv-LYS transformants. Some of the results are shown in Figure 5 (Western blot). Method: SDS-PAGE was carried out on 8-25% gradient gels using the Pharmacia Phast system or on homogeneous 12.5% home-made SDS-gels. For Western blot analysis a polyclonal anti-serum against Fv-LYS was used (1:1500) for the detection of both ScFv-LYS and ScFv-HCG. 2.6.1b Analysis by PIN-ELISA The amount of functional ScFv-LYS (as determined by a PIN-ELISA assay) in the medium of AWC(M) transformants is given in Table 2. Table 2 Transformant: construct ScFv-fragment mg/1 AWCM4155 #102 18 a.a. ss-glaA-ScFv-LYS 15 - 22 -11 AWCM4155 #105 same 3 AWC 4155 # 4 same 10 AWC 4155 # 5 same 2 AWCM4159 #101 prepro-"glaA2"-KEX2-ScFv-LYS 91 - 66 - 67 AWCM4159 #608 same 3 AWCM4159 #610 same 16 AWC 4159 #701 same 40 AWCM4161 #612 prepro-"glaA2"-KEX2-ScFv-HCG 4 AWC 4161 # 2 same 1 A. niger var. awamori mutant #40 0 The amount of ScFv-LYS in medium of AWC(M)4155 (18 a.a. glaA) transformants ranged from 2 to 22 mg/1. AWC(M)4159 (co-)transformants (prepro-"glaA2"- KEX2-construction) secrete up to about 90 mg/1 into the medium, while no production was found for the A. niger var. awamori mutant #40 strain. With the quantitative PIN-ELISA assay for the determination of ScFv-HCG it was found that AWC(M)4161 (co-)transformants ("glaA2"-KEX2-construction) secreted up to 4 mg/1 functional ScFv-HCG into the medium. However, in the medium of AWC4157 (18 aa glaA signal sequence) transformants no ScFv-HCG was detected. Method: PINs coated with either lysozyme or HCG were incubated with (diluted) medium samples. Subsequently the PINs were incubated with antiserum against Fv- SU5STITUTE SHEET (RULE 26 LYS and Fv-HCG respectively, then with goat-anti-rabbit conjugate with alkaline phosphatase. Finally the alkaline phosphatase enzyme-activity was determined after incubation with p-nitro-phenyl phosphate and the optical density was measured at 405 nm. Using standard solutions of Fv-LYS and Fv-HCG respectively, the amount of functional ScFv-LYS and ScFv-HCG was calculated. Example 3 Construction of Aspergillus niger var. awamori integration vectors for the production of ScFv fragments, using the endoxylanase pro- moter and terminator and a DNA sequence encoding the endo¬ xylanase secretion signal and the mature endoxylanase protein. Although this Example describes the construction of expression plasmids encoding fusion proteins between the mature endoxylanase protein and the ScFv fragment it is obvious that alternative expression plasmids can be constructed in much the same way in which only part of the endoxylanase protein is used. 3.1 Construction of pUR4158-A. After digesting plasmid pScFvLYSmyc (see Example 1.1) with .Pstl and Xhol, an about 0.7 kb Pstl-Xhol fragment could be isolated from agarose gel. This fragment codes for a truncated Single Chain Fv-Lys fragment missing the first 5 and the last 5 amino acids (see the nucleotide sequence (SEQ. ID. NO: 25) and deduced amino acid sequence (SEQ. ID. NO: 26) of the about 700 bp Pstl-Xhol fragment encoding the ScFv fragment of the monoclonal anti-lysozyme antibody D1.3 (ScFv LYS) given below.

The 5'-part of the coding strand of the synthetic DNA fragment codes for the KΕX2 recognition site (ISKR), a spacer (GGS) followed by the first 5 amino acids of the variable part of the antibody heavy chain. The 3'-part of the coding sequence encodes the last 8 amino acid residues of the variable part of the antibody light chain. Upon digesting the obtained plasmid with Pstl and Xhol a vector fragment of about 4 kb can be isolated. Upon ligating the about 0.7 kb Pstl-Xhol fragment of pScFvLYSmyc with the about 4 kb vector fragment, pUR4158-A can be obtained containing the restored genes encoding the N Η and N L antibody fragments. 3.2 Construction of pXYL2. Plasmid pAW14B was the starting vector for the construction of a series of expression plasmids containing exlA expression signals and genes coding for ScFv fragments. The plasmid comprises an Aspergillus niger var. αwαmori chromosomal 5.2 kb Sail fragment on which the 0.7 kb exlA gene is located, together with 2.5 kb of 5'-flanking sequences and 2.0 kb of 3'-flanking sequences (see Figure 6 = Figure 3 of UΝILENER's not prior-published WO 93/12237). Upon digesting pAW14B with Xbal and BamHl, an about 3.2 kb Xbal-BamHl fragment can be isolated comprising the exlA promoter, the exlA structural gene and part of the exlA terminator area. This fragment can be cloned into plasmid pBluescript (ex Stratagene) digested with the same enzymes, resulting in plasmid pXYLl. By applying PCR technology on the about 3.2 kb Xbal-BamHl fragment, it is possible to change the 3'-end of the exlA structural gene by replacing the last codon encoding serine and the stop codon TAA by the BamHl site GGA TCC followed by 8 other codons comprising an EcoRN site and an EcoRI site using a first (anti-sense) primer (A) given below (SΕQ. ID. NO: 31-34) and a second (sense) primer (B) also given below located upstream of the Seal site (located in the exlA gene). This sense primer corresponds with nucleotides 824-843 of Figure 1 of UNILΕNΕR's not prior-published W) 93/12237 forming part of the exlA gene. After digesting the resulting PCR product with Seal and EcoRI, an about 175 bp Scαl-EcoRI fragment can be isolated. Upon digesting pXYLl with Seal (partially) and with EcoRI (partially), an about 6 kb Scαl-EcoRI fragment, comprising the intact pBluescript DNA and the exlA promoter region and most of the exlA structural gene, can be isolated. Ligation of the about 175 bp Scαl-EcoRI fragment with the about 6 kb Scαl-EcoRI fragment ex pXYLl will result in a plasmid, called pXYL2, which differs from pXYLl in that the 3'-part of the exlA gene and the terminator fragment are replaced by the newly obtained Scαl-EcoRI PCR fragment.

This was achieved by partially digesting plasmid pAW14B with EcoRI and after dephosphorylation the linear 7.9 kb EcoRI plasmids were isolated and religated in the presence of the "EcoRT-Notl linker: 5'-AATTGCGGCCGC-3 * (SΕQ. ID. NO: 36). NotI After selecting a plasmid still containing the EcoRI site in the upstream area of the exlA structural gene, pAW14B-10 was obtained. Such selection method is known to a skilled person. Subsequently the Aflll site, located downstream of the exlA terminator was removed by partially cleaving plasmid pAW14B-10 with Aflll and religating the isolated, linearized plasmid after filling in the sticky ends, resulting in plasmid pAW14B-ll after selecting the plasmid still containing the Aflll site near the stop codon of the exlA gene. Such selection method is known to a skilled person. This plasmid pAW14B-ll can be used for construction of a series of expression plasmids comprising a DΝA fragment coding for a fusion protein consisting of the endoxylanase protein or part thereof and the ScFv fragment. Preferably the two protein fragments are connected by a protease recognition site e.g the KΕX2 cleavage site. (i) Upon digesting plasmid pAW14B-ll with NotI and Aflll, an about 4.7 kb fragment can be isolated comprising the pUC19 vector and part of the exlA terminator. (ii) Upon digestion of pXYL2 with NotI and EcoRN, an about 3.2 kb fragment can be isolated. Alternatively an Notl-BαmHl fragment of about the same length can be isolated. (iii) Upon digesting pUR4158-A with EcoRN and Aflll, an about 0.8 kb fragment can be isolated encoding the ScFv-LYS preceded by a short (linker) peptide comprising the KΕX2 cleavage site and a spacer (GGS). Alternatively, a BamHl-Aflϊl fragment of about the same length can be isolated, which fragment does not contain a DΝA fragment encoding the KEX2 cleaving site. A) For the construction of expression plasmids encoding the fusion protein consisting of mature endoxylanase and ScFv-LYS, the about 4.7 kb Notl-Aflll of pAW14B-ll, the about 3.2 kb Notl-βα HI fragment of pXYL2 and the about 0.75 kb BamHl-Aflϊl fragment of pUR4158-A are ligated resulting in pUR4455. B) For the construction of expression plasmids encoding the fusion protein consisting of mature endoxylanase and ScFv-LYS connected by the KEX2 cleavage site, the about 4.7 kb Notl-Aflll of pAW14B-ll, the about 3.2 kb Notl-EcoRN fragment of pXYL2 and the about 0.75 kb EcoRV-Aflll fragment of pUR4158-A are ligated resulting in pUR4456. The constructed expression vectors can subsequently be transferred to moulds (for example Aspergillus niger, Aspergillus niger var. awamori, Aspergillus nidulans etc.) by means of conventional co-transformation techniques and the chimeric gene com¬ prising a DΝA sequence encoding the desired ScFv fragment can then be expressed via induction of the endoxylanase II promoter. The constructed vector can also be provided with conventional selection markers (e.g. amdS or pyrG, hygromycin etc.), e.g. by introducing the corresponding genes into the unique NotI restriction site, and the mould can be transformed with the resulting vector to produce the desired protein, essentially as described in Example 2 of UΝILENER's not prior-published WO 93/12237. Example 4 Isolation of gene fragments of antibodies raised against (oral) microorganisms. Monoclonal antibodies raised against oral microorganisms have been described in the literature (De Soet et al; 1990), an example of which is OMVU10 raised against streptococci. For the production of ScFv fragments derived from these monoclonal antibodies the gene fragments encoding the variable regions of the heavy and light chains had to be isolated. The isolation of RNA from the hybridoma cell lines, the preparation of cDNA and amplification of gene fragments encoding the variable regions of antibodies by PCR were performed according to standard procedures known from the literature (see for example Orlandi et al, 1989). For the PCR amplification different oligonucleotide primers have been used, for the heavy chain fragment: A: 5'-AGG TSM ARC TGC AGS AGT CWG G-3' (SEQ. ID. NO: 37) Pstl in which S is C or G, M is A or C, R is A or G, and W is A or T and B: 5'-TGA GGA GACGGTGAC CGTGGTCCCTTG GCC CC-3' β stEII (SEQ. ID. NO: 38), and for the light chain fragment (Kappa): C: 5-'GAC ATT GAG CTC ACC CAG TCT CCA-3' (SEQ. ID. NO: 39) Sαcl and D: 5'-GTT TGA TCT CGA GCT TGG TCC C-3' (SEQ. ID. NO: 40). Xliol The heavy chain PCR fragment obtained in this way was digested with Pstl and .RstEII and a Pstl-BstEll fragment of about 0.33 kb was isolated. The thus obtained fragment can be cloned into pUR4158-A. To this end pUR4158-A is digested with Pstl and BstEϊl, after which an about 4.4 kb vector fragment can be isolated. Ligation of the above described heavy chain fragment of OMVUIO with the about 4.4 kb vector fragment will result in pUR4158-A10H. In this plasmid the heavy chain fragment of the lysozym antibody, which was originally present, is replaced by that of the OMVUIO antibody. The light chain PCR fragment obtained in a similar way was digested with Sαcl and Xhol, and a SαcI--Y7zoI fragment of about 0.3 kb was isolated. After digestion of pUR4158-A10H with Sαcl and Xhol, a vector fragment of about 4.4 kb can be isolated. Ligation of this vector fragment with the above described light chain fragment of OMVUIO will result in pUR4457. In this plasmid both the heavy chain fragment and the light chain fragment of the lysozyme antibody are replaced by the appropriate heavy and light chain fragments of OMVUIO. The nucleotide sequence (SEQ. ID. NO: 41) and the deduced amino acid sequence (SEQ. ID. NO: 42) of the Pstl-Xhol fragment present in pUR4457 containing the thus obtained gene encoding an ScFv fragment of OMVUIO is given below. The first 5 codons and the last 5 codons are given in Example 3.1 above showing the overlap with the Pstl and Xhol sites.

After digesting pUR4457 (see Example 4) with EcoRN and Aflll, an about 0.8 kb fragment can be isolated encoding the ScFv-OMNUlO preceded by a short (linker) peptide comprising the KΕX2 cleavage site and the GGS spacer. Alternatively, a BamHl-Aflϊl fragment of about 0.75 kb can be isolated for the construction of expression plasmids coding for fusion proteins not containing a KEX2 cleavage site. Upon ligating the thus obtained fragments with the fragments obtained in 3.3 (i) and (ii) in the same way as described in 3.3 B) and A), an expression plasmid can be obtained containing a DΝA sequence coding for a fusion protein comprising the endoxylanase protein and the ScFv OMVUIO fragment, either with (pUR4460) or without (pUR4459) the KEX2 cleavage site, respectively. Analogous to the method described in Example 3, the resulting plasmids (either with or without an added selection marker) can be introduced into Aspergillus. SUBSTITUTE SHEET (RULE 25) Example 6 Isolation of gene fragments of an antibody raised against human pregnancy hormone (HCG). In much the same way as described in Example 4, gene fragments coding for the variable regions of the heavy and the light chains of anti-HCG antibodies were isolated and can be cloned into plasmid pUR4158-A which results in plasmid pUR4458. The nucleotide sequence (SEQ. ID. NO: 7) and the deduced amino acid sequence (SEQ. ID. NO: 8) of the Pstl-Xhol fragment encoding the ScFv-HCG fragment were given above in Example 1.2. Example 7 Construction of expression cassettes for the production of ScFv fragments, using the endoxylanase promoter and terminator and a DNA sequence encoding the prepro-"glaA2" protein. 7.1 Construction of pAW14B-12. Plasmid pAW14B-12 was constructed using pAW14B-ll (see Example 3.3) as starting material. After digestion of pAW14B-ll with Aflll (located at the exlA stop codon) and BgUl (located in the exlA promoter) the 2.4 kb Aflll-Bglϊl fragment, containing part of the exlA promoter and the exlA gene was isolated. After partial digestion of this fragment with BspHl (located in the exlA promoter and the exlA start codon) the isolated 1.8 kb Bglϊl-BspHl exlA promoter fragment (up to the ATG) was ligated with the isolated 5.5 kb Aflll-Bglll fragment of pAW14B-ll, containing the exlA terminator, in the presence of the synthetic DNA oligonucleotides: (BspHI) Aflll 5 1 - CAT GCA GTC TTC GGG C -3' (SEQ. ID. NO: 43) 3'- GT CAG AAG CCC GAA TT -5' (SEQ. ID. NO: 44) B sl resulting in pAW14B-12. 7.2 Assembly of expression cassettes (i) Upon digesting pAW14B-12 with Bbsl (partially) and Aflll, an about 7.3 kb BspHl-Aflll vector fragment was isolated. (ii) From plasmid pAN56-4 (described in the above mentioned reference of M.P. Broekhuijsen et al.) an about 1.9 kb NcoI-EcoRN fragment was isolated, comprising part of the glaA gene, starting from the ATG initiation codon (which coincides with the Ncol site), and coding for the glucoamylase prepro part and the first 514 amino acids of the mature glucoamylase ("glaA2"). (iii) From the plasmids pUR4158-A (encoding for the ScFv-LYS fragment preceded by the KΕX2 recognition site and the GGS spacer: see Example 3.1), pUR4457 (encoding for the ScFv-OMNUlO fragment preceded by the KEX2 recognition site and the GGS spacer: see Example 4), and pUR4458 (encoding for the ScFv-HCG fragment preceded by the KEX2 recognition site and the GGS spacer: see Example 6) EcoRV-Aflll fragments of about 0.8 kb were isolated. Upon ligating (i) the BspHl-Aflll vector fragment, (ii) the NcoI-EcoRV glaA fragment (Ncol sticky ends are compatible with BspHl sticky ends), and either of the EcoRV-Aflll ScFv encoding fragments, a set of expression plasmids can be obtained. pUR4462 VexlA - prepro-"glaA2"-KΕX2-ScFv-LYS pUR4463 FexlA - prepro-"glaA2"-KEX2-ScFv-HCG pUR4464 YexlA - prepro-"glaA2"-KEX2-ScFv-OMVU10 After insertion of the amdS selection marker into the NotI site, the resulting plasmids were introduced into Aspergillus, as described in Example 3. 7.3 Production of ScFv-LYS Upon growth of the resulting Aspergillus niger var. awamori transformed with pUR4462 in a 10 litre fermenter, the culture medium was analyzed by polyacrylamide gel electrophoresis. Figure 7 shows the gel after it was stained with Coomassie Brilliant Blue and with arrows are indicated the released ScFv-LYS fragment and the fusion protein and/or the truncated glaA protein. The amount of "active" ScFv-LYS was determined to be about 250 mg/1. It is obvious that further optimization of the fermentation conditions or mutagenesis of the production strain will result in even higher production levels.
